Dynamically do something after a useState variable has been set?

−0

Since setState is asynchronously executed, how to dynamically do something after a useState variable has been set?

Consider

import { useState } from "react";
const [myVar, setMyVar] = useState("");

After

setMyVar("New String");

How to listen for that?
